Written by Blake Boege · Founder, Calculator Answers

A PDF page reorder utility is a document manipulation tool that restructures the internal page tree of a PDF file. By copying pages in a custom sequence index, it creates a new document with the rearranged ordering.

Rearrange the page sequence in your PDF file. Processed locally in your web browser for complete privacy.

How it works

When a PDF is loaded, pdf-lib reads the catalog and maps the count of internal page objects.

The custom comma-separated order is parsed. The script verifies that every listed page number is within the range of 1 to the document's total pages.

A new PDF document is instantiated. Pages are copied from the original file in the exact sequence requested using copyPages.

The pages are appended to the new PDF, saved, and triggered as a browser download.

In-Browser Processing. The entire operation is done on your local CPU. No web request containing your document data is sent.
